Meet Four New Virus-Fighting Technologies That Could Soon Become The Standard In Public Areas

As the push for some to head back to the office continues, despite being the midst of the ongoing pandemic, a focus has shifted to what kinds of technologies are going to be used in order to make sure that public areas, like office environments and airports, are virus-free.

Aside from the usual hand sanitizers and face masks, FT published a report this week highlighting some of the other technologies that businesses are choosing to employ in order to surfaces and spaces clean. 

Shaun Fitzgerald, visiting professor at the University of Cambridge, said: “Pandemics like this can provide fertile ground for creative minds to think about how to do things differently.”

One option that’s being looked at is self-cleaning surfaces. While the virus can stay alive for up to 72 hours on plastics and steel, silver and copper have a track record of killing viruses and bacteria within four hours. Felicity de Cogan, research fellow at the University of Birmingham and founder of NitroPep, said that timeframe needs to get down to “seconds to minutes” and it needs to be “built into the material”.

Her company is working on developing layers of materials with spike particles on them that puncture and kill viruses within minutes. Her company’s antimicrobial agents can be added to already existing desks, walls and other surfaces and rupture “anything with a membrane”. 

“It doesn’t require a change in behaviour, it just sits there and kills whatever lands on it,” de Cogan said. In a pilot run of the technology for a Royal Navy ship, it killed more than 95% of bacteria like E. Coli and MRSA. de Cogan aims to implement it in public transport and for self-cleaning equipment, if it proven to be able to kill coronavirus. 

Another option is UV irradiation. The idea of “germicidal ultraviolet” has been known for years but is now getting another look. UV beams are used to kill micro-organisms by targeting the RNA in viruses and DNA in bacteria and fungi. UV lamps have been found in the past to be effective in stopping drug-resistant tuberculosis in large rooms.

The technology is good for large rooms and crowded and poorly ventilated environments.
